2016年3月11日 · A Raman peak at 603 cm –1 appeared for all the four samples at OER-relevant potentials, ≥1.62 V vs RHE. This peak was identified as the Cu–O stretching vibration band of …

2023年10月19日 · We show that defects in Cu 2 O induce Raman activity in several modes that are purely IR-active or optically silent in pristine Cu 2 O and that the 3D structures improve the …

2019年7月12日 · The Raman spectra of all materials showed the characteristic phonon frequencies of the highly crystalline Cu 2 O and CuO. All Raman peaks belong to Cu 2 O or …

Raman results show that from the CH3CH2OH-N2 plasma mixture it is possible to obtain one of the Cu oxidation phases which corresponds to Cu2O due to the fact that within the sample …

2024年12月20日 · This study introduces a multifunctional device based on Cu2O/g-C3N4 monitoring and purification p–n heterojunctions (MPHs), seamlessly integrating surface …

We show that defects in Cu2O induce Raman activity in several of its modes that are purely IR-active or optically silent in pristine Cu2O. The experimental results are corroborated by linear …

2019年12月5日 · Raman, Fourier transform infrared (FTIR) spectroscopy and TEM imaging of the prepared NPs reveal the existence of additional minority CuO phase, not determined earlier …

2014年7月9日 · But, in contrast to most other crystalline materials, the Raman spectrum of Cu 2 O is dominated by infrared active and silent lattice modes rather than by the only Raman …

2008年12月22日 · Raman scattering an X-ray measurements demonstrates the existence of the single phase Cu 2 O. PL spectra were taken from 10 to 180K to define the main radiative …

2016年10月20日 · Octahedral Cu 2 O-Au composite microstructures (CMSs) were synthesized with a facile in situ method and were attempted as surface-enhanced Raman scattering …
